What is an adaptation?
A feature that enables an organism to survive in a particular environment.
Give two examples of plant adaptations in mangroves.

How does the Surface Area : Volume ratio change in animals in different environments?
- Animals is hot environments have increased surface area.
- Animals in cold climates have decreased surface area.
Give four adaptations an animal living at a Poles might have.
- Small extremities
- Blubber
- Thick fur
- Small surface area.
How do animals adapt seasonally to their habitat?
Arctic animals change the colour of their fur.
Why do animals camouflages?
